I am in terrible shape, and I think it might be the Quetiapine I am taking to help me sleep. I take 300 mg. every night. Every morning, I fee just horrible. I feel like I am going to burst into tears at any moment and I am just eaten up with horrible, unrelenting fatigue ( I guess that's what you would call it ) I am constantly holding my head in my hands, feeling like I am on the verge of a total nervous breakdown. Sometimes I get better in the afternoons, and sometimes I don't. I can't exist like this. Please help! Could the medication be causing me to feel this way?
